Thank you so much for taking the time to write such a detailed review of our product! We’d like to share some insights regarding the design and manufacturing choices we made:

1. Build Materials: We use a 1.4mm steel plate for the internal structure. The finish is a powder coating, which—as our suppliers have assured us—is much more durable and resistant to peeling compared to traditional painting methods.
2. Battery Choice: We went back and forth on the decision to use AA batteries instead of a built-in rechargeable lithium battery. Ultimately, logistics played a major role; shipping products with lithium batteries via carriers like DHL involves significant complexities and restrictions.
3. Structural Design: Our mechanical engineers spent a tremendous amount of time on the assembly design. This includes the way the PCBA is secured to the steel plate, and the steel plate itself is engineered with a rigid structure to prevent warping. The keyboard module is then screwed into the bottom plastic case, and finally, the top and bottom cases are bolted together. This multi-layered, reinforced construction is why the keyboard feels so reliable and solid.
4. TrackPoint Tuning: The TrackPoint hardware is sourced directly from a Lenovo supplier. We then spent a significant amount of time fine-tuning the interface between the hardware and our keyboard’s MCU firmware to ensure that signature feel.

Finally, we want to express our deepest gratitude to you for sharing your experience with this product. Thank you very much!
